Abstract

A system tool provides dispatchers in power grid control centers with a capability to manage changes. A user interface and a plurality of scheduler engines are provided. A comprehensive operating plan has multiple dispatch engines that are security constrained unit commitments and economic dispatch sequences with different look-ahead periods. The comprehensive operating plan is configured to integrate the dispatch engines into a unified scheduling system. The comprehensive operating plan has a data structure for capturing scheduling data, transaction scheduling, load forecast and time series data. The comprehensive operating plan is configured to coordinate scheduling data to and from power grid system applications and present a comprehensive, synchronized and harmonized view of scheduling data to at least one of, applications, power grid system operators and other stakeholders for power grid system operations.

Claims

1. A system tool that provides dispatchers in power grid control centers with a capability to manage changes, comprising:

a user interface;

a plurality of scheduler engines; and

a comprehensive operating plan with multiple dispatch engines 1, 2 and 3 that are security constrained unit commitments and economic dispatch sequences with different look-ahead periods, the comprehensive operating plan being configured to integrate the dispatch engines into a unified scheduling system, the comprehensive operating plan having a data structure for capturing scheduling data, transaction scheduling, load forecast and time series data, wherein the comprehensive operating plan is configured to coordinate scheduling data to and from power grid system applications and presents a comprehensive, synchronized and harmonized view of scheduling data to at least one of, applications, power grid system operators and other stakeholders for power grid system operations.

2. The tool of claim 1, wherein results from each dispatch engine are saved in the comprehensive operating plan and a composite is create and saved.

3. The tool of claim 1, wherein the comprehensive operating plan has at least one of, a presentation layer and a set of user interfaces of its own to support power grid system operator decision making.

4. The tool of claim 3, wherein the comprehensive operating plan has a service layer to provide a set of front end programming'"'"'s to interact with at least one of, external power grid system applications and data sources.

5. The tool of claim 4, wherein the comprehensive operating plan has a business application layer that performs at least one of, validation, translation, transformation, consolidation and harmonization of selected asynchronized scheduling data.

6. The tool of claim 5, wherein the comprehensive operating plan has a persistence data layer for some selected key scheduling data.

7. The tool of claim 6, wherein the class of scheduling data of interest is selected from at least one of, resource, megawatt schedule, demand forecast, outage schedule, transaction and interchange schedule, transmission constraint limit schedule, reserve and regulation requirement schedule and resource characteristics schedule.

8. A system tool that provides dispatchers in power grid control centers with a capability to manage changes, comprising:

a user interface;

a plurality of scheduler engines; and

a comprehensive operating plan with multiple dispatch engines 1, 2 &

3 that are security constrained unit commitments and economic dispatch sequences with different look-ahead periods, the comprehensive operating plan being configured to integrate the dispatch engines into a unified scheduling system, the comprehensive operating plan having a data structure for capturing scheduling data, transaction scheduling, load forecast and time series data, wherein the comprehensive operating plan is configured to coordinate scheduling data to and from power grid system applications and presents a comprehensive, synchronized and harmonized view of scheduling data to at least one of, applications, power grid system operators and other stakeholders for power grid system operations, wherein the comprehensive operating plan includes a repository of all operating plans in a multi-stage decision process.

9. The tool of claim 8, wherein each stage in a multi-stage decision process generates a set of schedules that are reflected in its corresponding individual comprehensive operating plans i.

10. The tool of claim 9, wherein aggregated results from the multi-stage decision process are captured in a total comprehensive operating plan t.

11. The tool of claim 10, wherein the comprehensive operating plan t is a merged outcome of individual comprehensive operating plans i.

12. The tool of claim 11, wherein at least a portion of individual operating plans i contents are not identical and allow for explicit translation/transformation between each individual comprehensive operating plan and the total comprehensive operating plan t.

13. The tool of claim 11, wherein multiple dispatch engines are coordinated using subordinate individual comprehensive operating plans i that are synchronized into the overall comprehensive operating plan t.

14. The tool of claim 11, wherein operator interaction through a user interface is with the comprehensive operating plan t.

15. The tool of claim 14, wherein the comprehensive operating plan contains individual resource level and comprehensive summary information.

16. The tool of claim 8, wherein the comprehensive operating plan includes power grid system level information selected from one or more of, power grid system/area demand forecast, and reserve requirements.
